One exception: Grub (and perhaps LILO) can boot from a RAID1 partition
because the individual partition looks like a plain file system. It
requires v 0.9 metadata which stores the superblock at the end of the
partition. (Don't ask me how I know! ;) )
I have used LVM to partition a RAID5. I have no idea if it adds
significant overhead vs. partitioning the RAID itself if that were
possible. It was arcane enough for me to not care to do it again. It
appears to have some powerful capabilities that were not needed by me.
best,
